After Decades of Speculation, Physicists Finally Confirm the Existence of "Time Mirrors"

Physicists have experimentally reversed electromagnetic waves in time, confirming a long-standing theoretical prediction. This breakthrough, achieved by Hady Moussa's team at CUNY, involves creating a temporal boundary in a transmission-line metamaterial, allowing part of the wave to retrace its path backward through time. This new method of wave control opens up possibilities for advanced spectrum engineering and frequency-selective devices.
